Heroic Games Launcher
Built on Electron, Heroic Games Launcher stores Chromium disk cache entries in Cache_Data along with GPUCache files that hold compiled shader data and other GPU process artifacts used by its web-based interface. These caches speed up loading of the library, store pages, images, and JavaScript resources, but after launcher updates, site changes, or graphics driver changes they can become stale or oversized. Kudu removes Heroic's Electron disk cache and GPU cache while leaving installed games, login sessions, settings, and account data untouched.
Why clean Heroic Games Launcher?
- Outdated Chromium disk cache entries can leave Heroic showing broken store artwork, missing game banners, or pages that never fully refresh after a launcher update
- Corrupted cached JavaScript or HTML assets can make the library view render as a blank window, incomplete sidebar, or endlessly spinning loading screen
- GPUCache data compiled against an older graphics driver can be invalid after a driver update, causing black windows, flickering interface elements, or stutter when the UI first draws
- An oversized Cache_Data folder slows Heroic's startup because Electron spends longer validating and pruning old web resources before the launcher becomes responsive
- Stale cached API responses and frontend assets can keep Heroic displaying outdated compatibility badges, store content, or login pages until the cache is rebuilt
- Damaged GPU process cache files can trigger random interface glitches such as invisible buttons, missing text, or menus that open with delayed repainting
